Description

Polsterauflage für Federkerne Zusatz zum Patent 1072 880 Die vorliegende Erfindung betrifft eine Polsterauflage für Federkerne und stellt eine zweckmäßige und vorteilhafte Weiterbildung des Gegenstandes des Hauptpatentes 1072 880 dar.Upholstery for spring cores Addendum to patent 1072 880 The present invention relates to a cushion for spring cores and represents an expedient and advantageous further development of the subject matter of the main patent 1072 880 .

Gegenstand dieses Hauptpatentes ist eine Polsterauflage für Federkerne, bestehend aus einem Hauptkörper nachgiebigen Materials, vorzugsweise Schaumstoff, dessen Ränder haubenartig abwärts gebogen sind und dessen untere, auf dem Federkern aufliegende Fläche mit einer Schutzschicht versehen ist, die aus schmalen, voneinander unabhängigen Streifen gebildet ist, die unabhängig voneinander mit dem Hauptkörper verbunden sind.The subject of this main patent is an upholstery for spring cores, consisting of a main body of flexible material, preferably foam, the edges of which are bent downwards like a hood and the lower one on the innerspring lying surface is provided with a protective layer, which consists of narrow, from each other independent strip is formed that are independent of each other with the main body are connected.

Der Erfindung liegt die Aufgabe zugrunde, den Gegenstand des Hauptpatentes fertigkeitsmäßig ganz erheblich zu verbessern.The invention is based on the object of the main patent to improve my skills considerably.

Es ist bereits bekannt, Gewebe- oder Faserlagen vorzubehandeln und mit einem Schaumstoffkörper bei der Herstellung desselben mechanisch und chemisch zu verbinden. Bei diesen bekannten Verfahren handelt es sich um eine ununterbrochene Schutzschicht, was nicht immer zweckmäßig ist.It is already known to pretreat fabric or fiber layers and with a foam body in the manufacture of the same mechanically and chemically connect to. These known methods are continuous Protective layer, which is not always useful.

Erfindungsgemäß ist bei der Polsterauflage für Federkerne nach Patent 1072 880 der den Hauptkörper bildende Schaumstoff ein Kunststoff, der durch das Aufschäumen die aus Gewebe-, Faservliesstreifen od. dgl. bestehende poröse Schutzschicht in an sich bekannter Weise durchdringt und chemisch mit ihr reagiert, so daß die Schutzschicht sowohl mechanisch als auch chemisch mit dem Hauptkörper verbunden ist.According to the invention, in the case of the upholstery for spring cores according to patent 1072 880, the foam forming the main body is a plastic which, by foaming, penetrates the porous protective layer consisting of fabric, fiber fleece strips or the like in a known manner and reacts chemically with it, so that the protective layer is both mechanically and chemically bonded to the main body.

Die Schutzschicht, aus dem die Streifen gebildet sind, kann aus Packleinwand, Baumwollgewebe, Leinen, Filz, Jute, Papier, Sisal oder anderen geeigneten Stoffen von gewebter Form oder als Kettwirkware bestehen. Die Schutzschicht kann ebenfalls aus Schnüren, Stricken, Seilen, Drahtnetz oder Gitter gebildet werden. Daneben kann die Schutzschicht kurze Fasern enthalten, wie z. B. Glasfasern von verschiedener Länge, Vorgarne u. ä., wobei die Fasern durch Blasen oder andere Verfahren zu einem Faservlies vereinigt werden.The protective layer from which the strips are formed can consist of packing canvas, cotton fabric, linen, felt, jute, paper, sisal or other suitable fabrics in woven form or as a warp-knitted fabric. The protective layer can also be formed from cords, cords, ropes, wire mesh or grids. In addition, the protective layer can contain short fibers, such as. B. glass fibers of different lengths, rovings and the like, the fibers being combined into a nonwoven fabric by blowing or other methods.

Erfindungsgemäß wird also eine Polsterauflage für Federkerne mit einer das Polster verstärkenden, verfestigten und zu einer Einheit verbundenen, die Federelemente abstützenden unteren Schutzschicht geschaffen.According to the invention is a cushion for spring cores with a The spring elements reinforce the cushion, solidify it and form a unit supporting lower protective layer created.

Weitere Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung, die an Hand der Zeichnung näher erläutert ist. In der Zeichnung zeigt Fig. 1 schematisch einen Querschnitt, der eine verbesserte Polsterauflage zeigt; Fig. 2 stellt eine vergrößerte Ansicht eines Details der Auflage dar, Fig. 3 bildet eine vergrößerte perspektivische Teilansieht der Polsterauflage und zeigt die Streifen der Schutzschicht.Further advantages of the invention emerge from the following description, which is explained in more detail with reference to the drawing. In the drawing, Fig. 1 shows schematically a cross section showing an improved cushion pad; FIG. 2 shows an enlarged view of a detail of the support, FIG. 3 forms an enlarged perspective partial view of the cushion cover and shows the strips of the protective layer.

In der in Fig. 1 und 2 dargestellten Ausführungsart der Erfindung besitzt der geformte Hauptkörper 10 aus Schaumstoff eine zurückspringende Auskehlung 12, um den oberen Rahmenrand 14 der Federkonstruktion 16 aufzunehmen. An der Unterseite des Körpers 10, in direkter Berührung mit der Federkonstruktion 16, befindet sich eine Schutzschicht, die gemäß dem Hauptpatent aus einzelnen schmalen, voneinander unabhängigen Streifen 18 gebildet ist. die unabhängig voneinander mit dem Hauptkörper 10 verbunden sind. Die Streifen sind zu einer Einheit mit der Oberfläche des Hauptkörpers 10 verbunden, der durch sie mit den Federelementen 20 in Verbindung steht.In the embodiment of the invention illustrated in FIGS. 1 and 2, the molded foam main body 10 has a recessed groove 12 to receive the upper frame edge 14 of the spring structure 16 . On the underside of the body 10, in direct contact with the spring structure 16, there is a protective layer which, according to the main patent, is formed from individual narrow strips 18 that are independent of one another. which are independently connected to the main body 10 . The strips are connected to form a unit with the surface of the main body 10 , which is connected to the spring elements 20 through them.

In der Praxis können die Streifen 18 aus leichtem, gewebtem Packleinen oder Baumwolltuch gebildet werden. Wenn, wie in dem Hauptpatent beansprucht, die Schutzschicht, aus der die Streifen 18 bestehen, zuerst einheitlich mit dem Körper 10 geformt wird, kann sie in einer geeigneten Formschablone eingespannt werden. Sobald der Stoff des Hauptkörpers in die Formschablone eingeführt wird und der chemische Aufschäumungsprozeß stattfindet, um die Formschablone auszufüllen, durchdringt der Stoff das Gewebe der Schutzschicht, um dieses fest mit dem Hauptkörper 10 zu verbinden, wobei der Stoff des Hauptkörpers 10 in der Formschablone in bekannter Weise aushärtet und die Schutzschicht so beschaffen sein soll, daß sie sich sowohl mechanisch wie auch chemisch mit dem Hauptkörper 10 verbindet. Nach Entfernung des Hauptkörpers 10 aus der Formschablone werden in die Schutzschicht die Schlitze 25 eingefräst, um so die Streifen 18 zu erhalten. Dabei kann für den Schaumstoff des Hauptkörpers jedes geeignete bindende oder klebende Material, das sich mit der Schutzschicht verträgt, angewendet werden, falls es die Lagen chemisch und mechanisch miteinander verbinden kann.In practice, the strips 18 can be formed from light weight woven packing linen or cotton cloth. When, as claimed in the main patent, the protective layer of which the strips 18 are made is first molded integrally with the body 10 , it can be clamped in a suitable mold. As soon as the fabric of the main body is introduced into the template and the chemical foaming process takes place to fill the template, the fabric penetrates the fabric of the protective layer in order to firmly bond it to the main body 10 , the fabric of the main body 10 in the template in a known manner Way cures and the protective layer should be such that it bonds both mechanically and chemically to the main body 10 . After the main body 10 has been removed from the template, the slots 25 are milled into the protective layer in order to obtain the strips 18. Any suitable binding or adhesive material that is compatible with the protective layer can be used for the foam of the main body if it can chemically and mechanically bond the layers to one another.

Der Hauptkörper 10, der in fester Verbindung mit der Schutzschicht geformt und gehärtet wird, kann verschiedene Eigenschaften aufweisen, die vom gewünschten Ergebnis abhängig sind. Bei der Verwendung von Polyester-Urethan-Schäumen erhielt man bei einer 2511/oigen Durchfederung einen Druckwiderstand im Bereich von 56 bis 84 g/CM2.The main body 10, which is molded and cured in integral connection with the protective layer, can have various properties depending on the desired result. When using polyester-urethane foams, a pressure resistance in the range of 56 to 84 g / cm2 was obtained with a 2511% deflection.

Bei Polyäther-Urethan-Schäumen erhielt man bei einer 25 11/oigen Durchfederung einen Druckwiderstand in der Größenordnung von 14 bis 35 g/cm2. Die Art der Polyester-Schäume erlaubt die Anwendung verhältnismäßig dünner Polsterlagen des Hauptkörpers 10, ohne daß die einzelnen Federelemente 20 spürbar werden. Jedoch erwecken die Polyester-Schäume nicht ein so weiches Gefühl wie die weichen Polyäther-Urethan-Schäume. Dagegen muß ein Hauptkörper von der Art der Polyäther-Schäume dicker sein, uni einen ebensoguten Schutz gegen ein Durchdrücken der Federeleinente der Federkonstruktion zu erzielen. Die Schutzschicht kann, mit Klemmschrauben eingespannt, so in der Schablon eangebracht werden, daß man damit die zurückspringende Kehle 12 ausgebildet und verstärkt. Bei einer Ausdehnung des Schaumes des Körpers 10 in der Schablone werden die Lücken in der Schutzschicht vom Schaum durchdrungen. Gleichzeitig reagiert das Diisocyanat in dein sich ausdehnenden Schaum mit den Reaktionsgruppen in dem Faserstoff der Schutzschicht. Dabei versteift sowohl die chemische Reaktion wie auch das Imprägnieren die Schutzschicht, die so zu einer wirkungsvolleren Isolierschicht gemacht wird. An der durch die Schutzschicht verstärkten Seite, die auf den Federelementen der Federkonstiuktionen ruht, wird der Schaumstoff des Hauptkörpers 10 bei Beanspruchung der Federelemente gegen Einreißen und Abrieb geschützt. Der Körper 10 kann also in geschichteter Ausführung eine obere Lage aus einem Polyäther-Schaum besitzen, um ein angenehmes Sitz-"efühl auf der Sesselkonstruktion des Fahrzeuges her vorzurufen, und eine untere Lage aus einem Polyester-Schaum aufweisen, der auch in dünnen Lagen ein ausgezeichnetes Isoliervermögen besitzt. Die Anwendung von Packleinen oder anderen Isoherstoffen, aus denen man die Schutzschicht herstellen kann, macht eine weniger starke und dichte Schaumlage oder der Schaumlagen des Körpers 10 erforderlich und trägt so zur Wirtschaftlichkeit des ganzen Sitzpolsters bei. Außerdem werden auch besser die Schaumstoffe, die den Hauptteil des Körpers 10 bilden, unterstützt.In the case of polyether-urethane foams, a compression resistance of the order of 14 to 35 g / cm2 was obtained with a deflection of 25 11 / o. The type of polyester foams allows the use of relatively thin padding layers of the main body 10 without the individual spring elements 20 becoming noticeable. However, the polyester foams are not as soft to the touch as the soft polyether-urethane foams. On the other hand, a main body of the type of polyether foams must be thicker in order to achieve just as good protection against the spring elements of the spring construction from being pushed through. The protective layer can be clamped in with clamping screws in the template so that the recessed groove 12 is formed and reinforced. When the foam of the body 10 expands in the template, the gaps in the protective layer are penetrated by the foam. At the same time, the diisocyanate in the expanding foam reacts with the reaction groups in the fibrous material of the protective layer. Both the chemical reaction and the impregnation stiffen the protective layer, making it a more effective insulating layer. On the side reinforced by the protective layer, which rests on the spring elements of the spring constructions, the foam of the main body 10 is protected against tearing and abrasion when the spring elements are stressed. In a layered design, the body 10 can therefore have an upper layer made of a polyether foam in order to create a comfortable seating "feeling on the chair structure of the vehicle, and a lower layer made of a polyester foam, which is also thinly layered The use of packing linen or other insulating materials from which the protective layer can be made requires a less strong and dense foam layer or the foam layers of the body 10 and thus contributes to the economy of the entire seat cushion. In addition, the foams are also better , which form the main part of the body 10 , supports.
